Title

kprobes: don't call disarm_kprobe() for disabled kprobes

Summary

In the Linux kernel, the following vulnerability has been resolved: kprobes: don't call disarm_kprobe() for disabled kprobes The assumption in __disable_kprobe() is wrong, and it could try to disarm an already disarmed kprobe and fire the WARN_ONCE() below. [0] We can easily reproduce this issue. 1. Write 0 to /sys/kernel/debug/kprobes/enabled. # echo 0 > /sys/kernel/debug/kprobes/enabled 2. Run execsnoop. At this time, one kprobe is disabled. # /usr/share/bcc/tools/execsnoop & [1] 2460 PCOMM PID PPID RET ARGS # cat /sys/kernel/debug/kprobes/list ffffffff91345650 r __x64_sys_execve+0x0 [FTRACE] ffffffff91345650 k __x64_sys_execve+0x0 [DISABLED][FTRACE] 3. Write 1 to /sys/kernel/debug/kprobes/enabled, which changes kprobes_all_disarmed to false but does not arm the disabled kprobe. # echo 1 > /sys/kernel/debug/kprobes/enabled # cat /sys/kernel/debug/kprobes/list ffffffff91345650 r __x64_sys_execve+0x0 [FTRACE] ffffffff91345650 k __x64_sys_execve+0x0 [DISABLED][FTRACE] 4. Kill execsnoop, when __disable_kprobe() calls disarm_kprobe() for the disabled kprobe and hits the WARN_ONCE() in __disarm_kprobe_ftrace(). # fg /usr/share/bcc/tools/execsnoop ^C Actually, WARN_ONCE() is fired twice, and __unregister_kprobe_top() misses some cleanups and leaves the aggregated kprobe in the hash table. Then, __unregister_trace_kprobe() initialises tk->rp.kp.list and creates an infinite loop like this. aggregated kprobe.list -> kprobe.list -. ^ | '.__.' In this situation, these commands fall into the infinite loop and result in RCU stall or soft lockup. cat /sys/kernel/debug/kprobes/list : show_kprobe_addr() enters into the infinite loop with RCU. /usr/share/bcc/tools/execsnoop : warn_kprobe_rereg() holds kprobe_mutex, and __get_valid_kprobe() is stuck in the loop. To avoid the issue, make sure we don't call disarm_kprobe() for disabled kprobes.

[0]  We can\neasily reproduce this issue.\n\n1. Write 0 to /sys/kernel/debug/kprobes/enabled.\n\n  # echo 0 \u003e /sys/kernel/debug/kprobes/enabled\n\n2. Run execsnoop.  At this time, one kprobe is disabled.\n\n  # /usr/share/bcc/tools/execsnoop \u0026\n  [1] 2460\n  PCOMM            PID    PPID   RET ARGS\n\n  # cat /sys/kernel/debug/kprobes/list\n  ffffffff91345650  r  __x64_sys_execve+0x0    [FTRACE]\n  ffffffff91345650  k  __x64_sys_execve+0x0    [DISABLED][FTRACE]\n\n3. Write 1 to /sys/kernel/debug/kprobes/enabled, which changes\n   kprobes_all_disarmed to false but does not arm the disabled kprobe.\n\n  # echo 1 \u003e /sys/kernel/debug/kprobes/enabled\n\n  # cat /sys/kernel/debug/kprobes/list\n  ffffffff91345650  r  __x64_sys_execve+0x0    [FTRACE]\n  ffffffff91345650  k  __x64_sys_execve+0x0    [DISABLED][FTRACE]\n\n4. Kill execsnoop, when __disable_kprobe() calls disarm_kprobe() for the\n   disabled kprobe and hits the WARN_ONCE() in __disarm_kprobe_ftrace().\n\n  # fg\n  /usr/share/bcc/tools/execsnoop\n  ^C\n\nActually, WARN_ONCE() is fired twice, and __unregister_kprobe_top() misses\nsome cleanups and leaves the aggregated kprobe in the hash table.  Then,\n__unregister_trace_kprobe() initialises tk-\u003erp.kp.list and creates an\ninfinite loop like this.\n\n  aggregated kprobe.list -\u003e kprobe.list -.\n                                     ^    |\n                                     \u0027.__.\u0027\n\nIn this situation, these commands fall into the infinite loop and result\nin RCU stall or soft lockup.\n\n  cat /sys/kernel/debug/kprobes/list : show_kprobe_addr() enters into the\n                                       infinite loop with RCU.\n\n  /usr/share/bcc/tools/execsnoop : warn_kprobe_rereg() holds kprobe_mutex,\n                                   and __get_valid_kprobe() is stuck in\n\t\t\t\t   the loop.\n\nTo avoid the issue, make sure we don\u0027t call disarm_kprobe() for disabled\nkprobes.\n\n[0]\nFailed to disarm kprobe-ftrace at __x64_sys_execve+0x0/0x40 (error -2)\nWARNING: CPU: 6 PID: 2460 at kernel/kprobes.c:1130 __disarm_kprobe_ftrace.isra.19 (kernel/kprobes.c:1129)\nModules linked in: ena\nCPU: 6 PID: 2460 Comm: execsnoop Not tainted 5.19.0+ #28\nHardware name: Amazon EC2 c5.2xlarge/, BIOS 1.0 10/16/2017\nRIP: 0010:__disarm_kprobe_ftrace.isra.19 (kernel/kprobes.c:1129)\nCode: 24 8b 02 eb c1 80 3d c4 83 f2 01 00 75 d4 48 8b 75 00 89 c2 48 c7 c7 90 fa 0f 92 89 04 24 c6 05 ab 83 01 e8 e4 94 f0 ff \u003c0f\u003e 0b 8b 04 24 eb b1 89 c6 48 c7 c7 60 fa 0f 92 89 04 24 e8 cc 94\nRSP: 0018:ffff9e6ec154bd98 EFLAGS: 00010282\nRAX: 0000000000000000 RBX: ffffffff930f7b00 RCX: 0000000000000001\nRDX: 0000000080000001 RSI: ffffffff921461c5 RDI: 00000000ffffffff\nRBP: ffff89c504286da8 R08: 0000000000000000 R09: c0000000fffeffff\nR10: 0000000000000000 R11: ffff9e6ec154bc28 R12: ffff89c502394e40\nR13: ffff89c502394c00 R14: ffff9e6ec154bc00 R15: 0000000000000000\nFS:  00007fe800398740(0000) GS:ffff89c812d80000(0000) knlGS:0000000000000000\nCS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 000000c00057f010 CR3: 0000000103b54006 CR4: 00000000007706e0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nPKRU: 55555554\nCall Trace:\n\u003cTASK\u003e\n __disable_kprobe (kernel/kprobes.c:1716)\n disable_kprobe (kernel/kprobes.c:2392)\n __disable_trace_kprobe (kernel/trace/trace_kprobe.c:340)\n disable_trace_kprobe (kernel/trace/trace_kprobe.c:429)\n perf_trace_event_unreg.isra.2 (./include/linux/tracepoint.h:93 kernel/trace/trace_event_perf.c:168)\n perf_kprobe_destroy (kernel/trace/trace_event_perf.c:295)\n _free_event (kernel/events/core.c:4971)\n perf_event_release_kernel (kernel/events/core.c:5176)\n perf_release (kernel/events/core.c:5186)\n __fput (fs/file_table.c:321)\n task_work_run (./include/linux/\n---truncated---"

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
